Whitley, along with second-ranked Astros prospect Kyle Tucker and five others, was assigned to Minor League camp on Tuesday. But with Houston playing two contests against St. Louis on Friday, the right-hander was given the chance to take the hill for another outing.

Harrison Bader reached on an error to start the night, but Whitley set down nine in a row until Drew Robinson worked a leadoff walk in the fourth inning. Marcell Ozuna drew his own free pass with one out, but Whitley set down the next two Cardinals, ending his night by fanning Matt Wieters.

Limited to 26 1/3 innings in eight starts in 2018 due to a 50-game suspension and a lat injury, the 2016 first-round pick has been dominant this spring with a 1.50 ERA and 15 strikeouts over 12 innings with the Major League club.

In other spring action:

Twins 12, Orioles 9

Fourth-ranked Twins prospect Wander Javier had a hit and an RBI before leaving early with a right quad strain in the win over the Orioles. Javier, who missed the entire 2018 season after having surgery to repair a torn labrum last May, exited after three innings "as a precaution for a right quad strain," MLB.com's Do-Hyoung Park reported. Luke Raley, the Twins' No. 26 prospect, added his first spring homer, a two-run drive in the third that plated Randy Cesar. Twins No. 6 prospect Brent Rooker singled and scored a run in the win. Orioles No. 25 prospect Drew Jackson belted a two-run homer in the sixth.
